To all whom t may concern:

- Be it known that we, CHARLES R. DRAKE and THOMAS H. BISHOP, of Rochester, in the county of Monroe and State of- New York, have invented certain new and useful Imrov'ements in Copy-Holders; and we do hereby declare the following to be a ful-l, clear, and exact description of the saine, reference being had to the accompanyingdraw-V ings, formin va part of this specification, and to the reerence-numerals markedtthereur present invention relates to copyholders of the type in which a copy plate carry- A ing the page or sheet'being followed and a line indicator spanning the copy plate are moved relatively to each other by mechanical means to successively indicate the lines of writing and it has for its obj ect to improve generally the construction of such machines whereby they can be made to work with greater smoothness and eliciency and with greater convenience to the operator. Certain vfeatures of the invention `are more particularly applicable to step by step machines of tlie` kind in which the line indicator is stationary and the copy plate moves rogressively up- .Ward 'past it and then has to he dropped again after the page has'been traversed and these features look toward providing an improved brake mechanism for regulating the fall so that it will be noiseless though reasonably rapid. The improvements are further directed toward the means for regulating the feed of the copy, toward the devices for holding the copy in place and toward a special construction of the frame or support whereby the working parts are housed and protected. To these and other ends the invention resides in certain improvements and combinationsI of parts -all as will be hereinafter more fully described, the novel features ,being pointed out inthe claims at the end' of the specication.

In the drawings:

Similar reference numerals throughout the several figures indicate the same parts.

Referring li'rst to the more general views, 1 lindicates the copy plate which is guided in a manner hereinafter described to move vertically-upon va-frame comprising a casing plate A2 having a-*forw'ardly turned flange 3 at the bottom, forwardlyturned flanges 4 at the sides and a forwardly turned flange 5 at the top (Fig. 6). The bottom flange 3 is reinforced by an angle bar 6 which embraces- 4 the casing plate at this point, being preferably riveted thereto as shown at 7. At the left hand end, .the bar 6 has a rearward eX disposed as far v e, while at the other end, iat-extends laterally-beyond the tension 8 forming a base leg casing plate and thence forwardly at 9 to be secured by a bolt 10 to a relatively transverse side arm 11 which extends forwardly tobottom of the copy platel on the rear side has upper and lower reanwardly turned guide flanges 17 and 18 at each side that travel on these guide rods 15 while a further ear 19 on the plate`16 holds the lower end of a movable guide rod 20 that is uided in the upper flange 5 and is carried by the copy plate 1. It is secured to the latter at the top by passing at 21 through a rearwardly turned flange 22 on a plate 23 (Figs. 3, 5 and 6) fixed to the rear side of the copy plate and which carries the copy holding clip as will be later described. In this way, three guiding elements are provided, one in the center and two at the sides.

The copy plate 1 is elevated with a step by step movement, the intervals of which are equal to the spacing between the lines of copy by a clutch plate 24 that engages the rod 20 above the flange 5. We prefer to call this rod l20, for this reason, the lifting rod. The clutch 24 is loosely fulcrumed at 25 upon =a reciprocatory rod 26 guided at its upper end in the flange 5 and pivoted at its lower end at 27to a transversely extending actuating rod 28 pivoted at 29 to the casing plate 2 and having its swinging end operating through a slot 30 in a side flange 4 of the casing plate. The clutch normally grips the rod while at a downward angle in a well known manner and raises the copy plate at each upward actuation of the clutch rod 26 an equal distance. As the clutch rod 26 returns to lowered position, the clutch slides down the rod 20 to take a new grip, being prevented from gripping it in the other direction by a downwardly curved extension 31 on the upper end of the clutch rod 26 that forms an abutment close to the' surface of the lifting rod 20.

While the lifting` clutch 24 is returning to lowered position between each actuation of the copy plate, it is necessary to hold the latter in the position to which it has been elevated and for this purpose, a retaining clutch 32 is mounted on a fixed fulcrum 33 carried by the casing plate 2 to engage the lifting rod 20 in much the same manner as the lifting clutch 24. Both clutches are inoperative when maintained in a horizontal posit-ion. The retaining clutch 32 is n ormally held in a depressed operative position by a leaf spring 34 secured to the flange 5 at 35 on the other side of the rod 20 and having a forked end 36 that embraces the rod20 and causes the gripping end of the clutch to bite thereon. This spring 34 is stronger that a spring 37 which acts between the support and the actuating lever 28 to hold the latter depressed and the lifting clutch 24 in the normal position shown 1n Fig. 3 at which time an abutment 38 on the clutch rod 26 is drawn against the retaining clutch 32 on the other side of its fulcrum. In Fig. 5, the parts are shown in the positions they assume at the end of the lifting movement. When it is desired that the; copy plate shall fall to its lowermost position, the actuating lever 28 is further depressed to a greater extent that the spring 37 can effect this movement whereupon the lifting clutch 24 is straightened out on top of the flange 5 and the retaining clutch 32 is rocked to a horizontal position against the tension of spring 34 by the abutment 38. The lifting rod 20 is then free to slide through both clutches until the guide flanges 18 on the copy plate rest upon buffer springs 39 encircling the guide rods 15 at the bottom of the casing.

An operating lever 40 is pivoted at 4l on the forwardly extending side arm 11 and is suitably connected at its rear end with the actuatinglever 28 whereby it will be seen that when the operator -depresses the forward end of the lever 40, the copy plate is elevated and when he lifts upon the lever 40 or reverses it, the clutches will be thrown out and the copy plate lowered. j

1n order to limit the throw of the operating mechanismand hence the extent toI which the clutch 24 will lift the copy plate at one actuation whereby the feed of the vmachine is rendered adjustable to the line spacing of different copy, we provide an adjustable gage plate 42 which is secured to the flange 4 labove the slot 30 by means of a clamping screw 43 provided with a nut 44 which screw passes through a longitudinal slot 45 in the plate 42. The lower end of the latter is provided with a laterally turned foot 46 that projects through the slot 30 and travels vertically thereinduring the adjustments of the plate. This foot 46 forms an abutment limiting the upward thrust of theactuating lever 28 and by so doing, limits the extent to which the copy plate is lifted at a given actuation of the lifting clutch 24.

The stationary line indicator is const-.ltuted, in the present instance, by a narrow plate 47 rotatably mounted on a yoke 48 on which it will frictionally hold itself in any given position of adjustment. The yoke, in turn, is similarly adapted to swing in friction bearings 49 formed partly by bracket plates 50 secured to the front face of the casing plate 2 and partly by the casing plate itself whereby the indicator 47 may be swung tovr'aised or lowered positions against the copy `plate or to an intermediate position spaced from it to facilitate the insertion its descent is apt to be severe and to be too great for mere buffer springs, such as those shown at 39 ,to absorb; We have therefore devised a retarding device in the form of a friction brake which is best shown in Fig. 5, the purpose of which is to prevent the copy plate from accumulating too great a velocity. It consists, in the present instance, of a lever 51 pivoted at 52 to the casing plate 2 on one side of the lifting rod 20, while on the other side of the rod, a resilient friction shoe 53 is carried by one end of the lever to bear against the said rod, as shown. The other arm ofthe lever extends upwardly at 5l and is provided with a flange 55 through which freely passes-a pull rod 56, the upper end of which latter projects through an enlarged opening 57 in the flange 5 and is capped by a nut 58., Between the cap and the fiange is a nut 59 that is threaded on the rod and constitutes a vertically adjustable abutment coperating with the flange 55 through the opening 57 which is large enough for its free passage. y

The lower end of the pull rod 56 is pivoted at 60 to a rock arm 61 pivoted to the casing plate 2 preferably on the same center 29 upon which the actuating lever 28 turns.`4

The lever 61 has a saddle 63 by engagement with which the actuating lever 28 interlocks with said rock arm when the actuating lever is sufiiciently depressed, but in the ordinary movements of the latter during the raising of the copy plate, this engagement does not occur as the downward movement of the actuating lever is not of sufiicient amplitude. When, however, the operating lever -lO is lifted or reversed and the actuating lever 28 is thereby abnormally depressed to throw out the clutches 24 and 32. the actuating lever engages the saddle 63 and causes a downward pull on the rod 56. This downward pull through the medium of the nut 59 is communicated to the lever 51 and by rocking the spring shoe 53 into heavier engagement with the lifting rod 20, the said lever administers a retardingl action on the downward sliding movement of the rod and constitutes an effective brake. The retarding pressure on the rod may be made greater or less by lowering or raising the nut 59 to increase or lessen. the throw of lever 51 and this nut is readily accessible from the ex terior of the machine. The cap 58 is merely for the purpose of preventing the nut 59 from becoming wholly detached.

The plate 23 previously referred to as supporting the upper end of the lifting rod 20 also .carries the devices for holding the copy and for this purpose it is provided at each end with a vertically extending rearwardly turned fiange 64 (Figs. 3, 9 and 10). Near the top of the flange which rises above `the upper edge of the copy plate 1 is a bearing'65 in the form of a slot opening at 66 at the rear edge of the flange. The paper holding clip 67 is preferably colnposed of a rod or wire extending across the face of the copy Iplate, as shown, and looped at each end to form a gripping portion 68 from each of which gripping portions, the material proceeds upwardly at 69 and thence inwardly at 70 to occupy the bearing 65y in which it turns to operate the clip toward and from the face of the copy plate, as shown in Figs. 9 and 10 whereby the copy may be admitted or removed. Beyond the bearing portion 70 each end is turned rearwardly again to terminate in an eccentric projection 71. Secured at 72 to the plate 23 is a suitably inclined spring arm 7 3 having a friction face 7 -l with an adjacent stop shoulder 75 furnished by a bend inl the arm. lhen the clip is in operative position, as shown in Fig. 9, the spring bears upon the eccentric projection 71 thereof in such manner as to hold the clip with a resilient pressure against the copy or against the face of the plate 1, and when the clip is raised to the inoperative position of Fig. 10, the eccentric projection .71 slips down the friction face 74 until it abuts the shoulder 75 which limits the opening movement of the clip. The spring arm 7 3 will then exert its pressure on the eccentric 7l in such manner as to hold the clip open, the said eccentric having passed to the other side of the center of movement, as will be understood.

This construction of thepaper clip is a great advantage in assembling the machine for two reasons, first, this copy-holding device is complete in itself on the plate 23 and may be set up inV its entirety and then secured to the plate l. Secondly, by means of the open bearings 65 tarnished b v the slots 66, the clip 67 is made easy to attach or remove, it being simply necessary to displace the spring arm 73 and slip the portion 70 into the slot 66 and then replace the spring arm in contact with the projections 71.

For the purpose of holding the copied pages in the position in which they are folded back over the top of the copy plate 1, we provide a light tightly coiled spring 76 that is held under slight `tension parallel with the top edge of the plate 1 and closely adjacent thereto by securing its endls in the flanges 64. It will be seen that this device can readily be displaced by lifting it at its center to thrust the page under it, whereafter it will resume its straightened position and clamp the paper between itself and the top edge of thevcopy plate.

It will be observed that the casing plate 2 protects the working parts at all times from the rear of the machine, while the copy plate 1, when in its lowered position, which is the normal position when not in use, completely covers the mechanism in front and together with the casing plate 2, completes a housing, that fully protects the mechanism and parup with accumulations of dust. Theustructure referred to also lessens the weight of the machine while increasing its strength, as the continuous nature of the plate 2 allows it to be made of light material with accom- 5 panying rigidity. The flanges 3, 4 and 5 on the plate 2 provide a continuous rectangular frame that supports all the working parts in practically one plane.

It is not thought necessary` to touch upon the general advantages of a machine of this type such as its applicability to use with a typewriter, as this type of machine is well known.
